You want to know if the command line you have is 32 or 64 bit
First of all, you need to open a command prompt. An easy way to find out whether you have a 64-bit or 32-bit command prompt is to use the following command:
CMD>set | find "PROCESSOR_ARCHITECTURE"
If the above command returns "PROCESSOR_ARCHITECTURE=x86", then you're using a 32-bit command prompt and when it delivers "PROCESSOR_ARCHITECTURE=AMD64" then you're using a 64-bit one.
On a 64-bit system you can run both command promps. The 64 bit one is located in c:\windows\system32 and the 32 bit one under c:\windows\sysWOW64.
You are reading right, in system32 you will find 64 bit applications and in sysWOW64 you will find 32 bit applications. This is by design.
